Abstract

Castor is an important oil crop. Impact damage is critical in the process of castor capsule shelling, directly affecting the shelling effect of castor seeds. An experiment was taken to investigate it. To study the damage degree of castor capsule under the impact, water content, impact height, and impact angle were taken as test factors, and the maximum impact force and normal deformation were taken as test indexes. The combination optimization was carried out through the multi-objective genetic algorithm. The results show that the impact height has a significant effect on the maximum deformation (p<=0.01), and the water content and impact angle have a significant impact on the impact force (p<=0.05). The height and angle have a significant impact on the deformation (p<=0.01), and the water content has a significant impact on the deformation (p<=0.05).

蓖麻是重要的油料作物。蓖麻种子脱壳过程中大量存在冲击现象，直接影响蓖麻种子的脱壳效果。为研究蓖麻蒴果冲击时的损伤程度，以含水率、冲击高度、冲击角度为为试验因素，最大冲击力和法向变形量为试验指标，进行试验，通过多目标遗传算法进行组合优化。结果为，碰撞高度对最大变形量的影响极显著，含水率和碰撞角度对冲击力的影响显著；碰撞高度和碰撞角度对变形量的影响极显著，含水率对变形量的影响显著。
